This is a one size fits all medium bulky weight hat designed to fully cover the ears with the ribbed brim turned up or down.  The green brim and top of the hat are Corriedale wool.  The lumpy purple is also Corriedale.  The bobble is knitted onto the hat and tacked down.  It's made of black Merino wool blended with white malamute hair and plied with sparkly silver/fuchsia cord. The gray fuzzy looking section around the green at the top is the same yarn along with some malamute/gray wool/silk/blue angelina blend.  Angelina is sparkly fiber that can be spun in with other fibers. The central lumpy section has more of the wool/malamute with sparkly cord along with some purple wool with white mohair blend that's been plied with dark red tencel. The lumpy section next to the ribbing is a blend of wool, mohair, malamute/silk and more of the blue angelina.
